Just because a BSTR has a separate length that does not make it in any way
similar to a Fortran allocatable array. The Fortran standard says little if
nothing on the machine representation of an allocatable array, but even if it
did, that would not help you at all in accessing BSTRs.

Intel Visual Fortran and Compaq Visual Fortran (and perhaps other compilers)
provide routines for reading and writing BSTRs and SafeArrays. If you'd like
more pointers and an example, ask in our user forum (link below).

My recollection is that the data in a BSTR is UNICODE.
